Question

a²-b²-a-b factorise the polynomials ​

Answer 1

Step-by-step explanation:

The factors of given expression is (a+b)\ \text{and}\ (a-b-1)(a+b) and (a−b−1) .

Step-by-step explanation:

We need to factorize a²-b²-a-b.

For this use formula a^2-b^2=(a-b)(a+b)a2−b2=(a−b)(a+b)

\begin{gathered}a^2-b^2-a-b =[(a-b)(a+b) -(a+b)]\\\\a^2-b^2-a-b =(a+b)[(a-b)-1]\\\\a^2-b^2-a-b =(a+b)(a-b-1)\end{gathered}a2−b2−a−b=[(a−b)(a+b)−(a+b)]a2−b2−a−b=(a+b)[(a−b)−1]a2−b2−a−b=(a+b)(a−b−1)

So, the factors of given expression is (a+b)\ \text{and}\ (a-b-1)(a+b) and (a−b−1) .
